<para>This class is the primary class for accessibility support via the
Accessibility ToolKit (ATK).  Objects which are instances of
<link linkend="AtkObject"><type>AtkObject</type></link> (or instances of AtkObject-derived types) are queried
for properties which relate basic (and generic) properties of a UI
component such as name and description.  Instances of <link linkend="AtkObject"><type>AtkObject</type></link>
may also be queried as to whether they implement other ATK
interfaces (e.g. <link linkend="AtkAction"><type>AtkAction</type></link>, <link linkend="AtkComponent"><type>AtkComponent</type></link>, etc.), as appropriate
to the role which a given UI component plays in a user interface.</para>
<para>All UI components in an application which provide useful
information or services to the user must provide corresponding
<link linkend="AtkObject"><type>AtkObject</type></link> instances on request (in GTK+, for instance, usually on
a call to <link linkend="gtk-widget-get-accessible"><function><link linkend="gtk-widget-get-accessible"><function>gtk_widget_get_accessible()</function></link></function></link>), either via ATK support
built into the toolkit for the widget class or ancestor class, or
in the case of custom widgets, if the inherited <link linkend="AtkObject"><type>AtkObject</type></link>
implementation is insufficient, via instances of a new <link linkend="AtkObject"><type>AtkObject</type></link>
subclass.</para>
<para>See also: <link linkend="AtkObjectFactory"><type>AtkObjectFactory</type></link>, <link linkend="AtkRegistry"><type>AtkRegistry</type></link>.  (GTK+ users see also
